METHOD 0F AND APPARATUS FORV APPLYING SWATCHES Filed Jan. 25, 1941 v sheets-sheet 7 Patented July`- 27,Y 1943 Vapparatus i lIn order to insure positive withdrawal of a swatchv from its supply magazine by the suction headmaking Contact therewith, and'to grip the Y swatch securely so-that it will not slide or skid relative to the suction head from thel time it is grippedv until it is attached tothe mounting sheet, I have foundit highly desirable to! draw the swatch downsinto the suction openings of the head tov a substantial extent to insure a dependable grip, but that results inthe margins of the gripped switch being turned upwardly and wrinkled or puckered to a substantial extent.

Preferably the suction medium is applied ap proximately to the'rear half of `a gripped swatch, the suction head being so designed that the forward edge of the swatch projects a substantial distance rforwardly vof the head. Itis another object of my invention toprovide automatically operating means adapted to iiatten the forward or 'free portion of a gripped swatch preparatory to .the securing of the swatch at its said forward or freeaportio'n to the mounting sheet.

It is ,another object ofV myinvention to provide automatically operating meansfor applying pressure tothe forward-or free portionof theiswatch upon the yswatch arriving at its proper position the spots-onl theY mountingsheet to which glue had previously been applied. Preferably the pressure applying mechanism andthe swatch flattening mechanism are timed to operate so that the atteningzmeans will tend to guide the freeor forward portion ofi-a swatch underV the pressure device, and preferably also the pressure `device draws the forward or rfree portion of the swatch down around. the forward edgejof the suction head, the forward extremity of the swatch being pressed Vin a, smooth vcondition Vonto the mounting sheet, and allv before Athe gripr on lthe swatch isjreleasedor any. skidding or`sliding of theswatch relative to the headtakes place.;

The apparatus Ydisclosed is intended to apply rtwo swatches'fat a timeandl it is intended to :t press! each..l lswatch yinto contact withy two glued in detail inV Figs. 1011014.

In theoperation of the mechanism, the glue fingers I I9 move from the position shownin full linesfto the position shown in dotted linesr(Fig.

` 10) traversing an arc of approximately 255. The

y'roller |0911l is in engagement with its cam. The y e rockv shaft; |04 has fixed'to it a pair of arrns ||2 between and in whiohis journaled a rock shaft MII3. The shait,. 96carrying the glue roller has fixed to it a ratchet wheel `I I4, said shaft and `Vratchet wheel. normally fturning in the direcluc Qtotal number ofrl teeth von'fthq;ratchet by the .v number of, teeth over whichzthe pawl |I5 rides VVVwl'i'enth-e ratchet is adyanced by the v.other pawl here will be at least' one 'extratooth With this ...arrangement arfresh surfacelion jthe glue roller i f5, is y always presented' to the glue Viingers Vnow to |29 mounted-Yon the table ,42.

meansfor moving the glue fingers from one posi-` tion to the other includes a gear member |24 fixed on the shaft H3 (Figs. 4, 5 and 13'), Ysaid gear member |124 meshing with a stationaryY gear member |25 loose on the shaft |64.r As shown in Fig. 13, the bottom edge vof said` gear member |25 is flat and bearsagainst the top side of the table d2 thereby preventing rotative movement of saidgear member. Since" the arms||2 are iixed to the shaft `Iii@ it lwill bek apparent that when link' |08 moves upwardly its rack yIIlI will rotate the shaft |06 in a counter-clockwise direction, and therefore the arms ||2 will move upwardly from the full line position tothe dotted line position (Fig: 10).` As said arms I|2 swing Y upwardly thevgear member |24 fixed to the shaft I I3 will cause said shaft to rotate counter-clockwise Vand the glue fingers ||9,ftherefore,-will be turned from the 'position shown in Vfull lines to the position shown in ldotted llines (Fig. 10)', and ofcourse when the link |08V and its rack move Awith theV surfacel of the `glueroller1rv g'may be varied considerablybylengthening or shortening said members |23 or by adjusting the sleeves I2! with respect to the fingers IIS. Since'the glue ingersarefturnable'on the .shaft II3, aY

further adjustment lmay be obtained by loosening theset screws |2Ilv and tilting the fingers ||9 to one side or the other on` the shait II3.

There is a tendency for' themounting sheets tolstick to ther glue applying members and to'be vraised therewith'. To obviate such tendency I "have provided across bar |26 (Fig. 4) mountedV Vat'its ends on the table.: Thebar IZB-.carries stripping lingers ITI-which project between 'the l glue applying fingers and since saidl stripping fingers are stationary theystrip the glued mounting sheets'from the glue'iingers when they latter are raised. -As shown in Fig. 4, I providean inclined ange |26a on the cross bar |26 to facili'- tate entry of the forward Yedges of the mounting sheets under saidrbar'. y vSwatch. dripping and transfer mechanism i As shownjinj Figs. fl and5, stacks of 'swatches and paper, like 'the stack shown in' Fig. 3, are placed in magazinesY |28.secured Vto a Asupport The magazines ,are losedattheirisides and atthe rear -(Fig; 4) and they are mountedlrso that their lower ends terminatefa substantial distance abc-ve the table (Fig. 5). Each magazine at itsbottom'is-piovided with 'spaced= ledges :|30 ion y which the lower end or theA stack rests.; A' :follower block or to the swatch'receiving position the end Iof the screw |18 bears against a portion ofthe mounting bracket |29 (Fig. 5), the spring It@ (Fig. 6) oper- :atingto hold theiadjusting screw of .the arm tight .againstthe mounting bracket.-Y

.The means for applying suction to the swatchesV Awillfnow be described..
